SAW-GAGE.

peeification of Letters Patent. V Patented 6, 1920.

Application filed January 3, 1919. Serial No. 269,394.

To all whom-it may concern:

Be it known that I, NEWTON ALLEN, citizen of the United States, residing at Lyons, in the county of Linn and State of Ore on, have invented certain new and useful mprovements in Saw-Gages, of which the following is a specification. Q

This invention relates to metal tools and implements, and more especially to dressing and jointing saws; and the object of the same is to produce a tool by which the teeth of ordinary cross cut sawscan be gaged and jointed.

The invention includes means for adjusting the block through'which the raker teeth project so that the tips of the same can be filed off to the desired relative length with respect to the other teeth.

The invention also includes a file clamp, for a purpose yet to appear.

Details are set forth in the following specification and claim.

Referring to the drawings Figure 1 is a front elevation Fig. 2 is a rear elevation, and

Fig. 3 is a vertical section on the line 33 of Fig. 2.

Fig. 4: is a vertical section on the line 4-4 of Fig. 1.

The body 11 has openings 11 for the sake of lightness and through which the fingers may be passed, and is provided along the upper edge of its front face with a flange 1 and along its rear face with two flanges 2.

and 3. A portion'of flange 1 is cut away as indicated at 5 and the cut extends down into the bod 11 so as to produce a large opening. ithin the opening moves a block 6 having an opening or slot 7 for the reception of the raker teeth R shown in dotted lines in Fig. 1 when the ordinary teeth T of the saw S underly the flange 1.- Screws 8 are threaded upward in the body 1 and their unthreaded and headed upper ends 9 are rotatably mounted within sleeves 9 carried by the block 6, and by turning these screws simultaneously in the same direction the position of the block within the recess or opening 5 may be very accurately adjusted so that its upper face will almost exactly ,aline with the lower face of the flange 1. The use of the device as a saw gage is indicated in Fig. 1 and well known to those familiar with this art. A striking feature of my improvement is the provision of indicating marks 20 and 21 in the ends of the opening 5, as best seen in Fig. 4,

one set of these marks being graduated to v just what position this block is adjusted and therefore, how much of the tips of the raker teeth should be filed off.

On the back of the body. 11 is mounted a jaw 10, the upper portion of the jaw 10 being open as indicated at 12 for the reception of pin 13 whose stem is threaded in the body and whose head constitutes a nut as shown at 14 in Fig. 3. The body'of the jaw has an upright groove 15 in which lies screw 16 threaded upward through the nut 14:, and the head 17 of the screw underlying the lower end of the jaw and the other end of the screw underlying the top of the open portion of frame 12. Therefore, by turn- I ing the screw the entire jaw can'be raised or lowered within the opening 4 through the two flanges 2 and 3. Coacting with the upper end which is the active face of this jaw, are two studs, 18 and 19, inserted in the body 11 of the tool and preferably near the ends thereof. The use of this device is well known to those familiar with the art. A file F is indicated in dotted lines as clamped beneath the studs and abovethe jaw when the latter .is adjusted by turning the screw. This file is for jointing the saw teeth as is understood.

The foregoing description and the drawings have reference to what may be considered the preferred, or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the ap ended claim.

aving thus fully described my invention what I claim as new anddesireto secure by Letters Patent is In a device of the character described, the combination of a body having an elongated opening extending thereinto from its upper edge, a block extending longitudinally of said opening, screws threaded throughthe body and extending into said opening, whereby the screws will not be exposed upon either side of the body and will thus be protected from injury, said screws having heads upon their upper ends, sleeves surrounding the screws contiguous to said heads and being carried by said block, whereby as the screws are rotated, said block may be moved within said opening as de sired.

In testimony whereof I afiix my signature in presence of two witnesses.

NEWTON ALLEN.
